Northern Territory Satellite Notes

Mainly high jetstream cloud spreading over the southern NT is causing over a little light rain. Patchy cloud over the Top End in a weak region of low pressure is generating the odd shower and storm. Skies are clearer elsewhere due to a ridge of high pressure.

Lightning Data Upgrade - NEW

Lightning Events

lightning Lightning strikes are displayed as crosses (ground events) or squares (cloud events) and fade from white (current) to red (30 minutes ago) to blue (60 minutes ago).

In December 2014 we upgraded our lightning network to the latest in sensor technology as used by the world's leading meteorological agencies. This has resulted in changes and improvements to the lightning data you will now see. The main changes are:

  • Much better detection of cloud to cloud strikes. Our upgraded network detects more CC strikes and better reflects research that shows typical storm cells produce approximately 75% cloud strikes and 25% ground strikes.
  • We have modified the display to show cloud to cloud strikes in smaller boxes and ground strikes above as "+" symbols. Temporal colouring remains the same.
  • Greater network coverage right across the country.
